How to substring the URL in Javascript

[priyanka9289]

Hello all, 

I am stuck with the code to use substring in javascript to extract the part of URL. 

https://abc.com:9001/xyz/myrequest

I need to extract only /xyz

Thanks in advance.

Change to "print" , as I said refer to Apigee javascript samples and make adjustments.

print("Original address: "+url_add)
print(break_address(url_add))

Add the javascript in the blog post to a javascript policy to extract the parts of the url to derive what you need.

I need to write javascript. The webpage doesn't return the script. If you know how to write the script, please let me know

Explain your use case. You will be using a javascript policy in your Apigee flow and the javascript source will have the following source (adjust to fir your requirements needs):

function break_address(url_add) {
    var data = url_add.split("://")
    var protocol = data[0];
   data = data[1].split(".com");
    var domain = data[0];
    data = data[1].split("/");

    if(data[1]){
        return [protocol,domain,data[1]]
    }
    return [protocol,domain]
}

var url_add = "https://www.w3resource.com/javascript-exercises/"
console.log("Original address: "+url_add)
console.log(break_address(url_add))

console command is giving error as it is not defined.

You don't need javascript for this. In the URI you provided - https://abc.com:9001/xyz/myrequest - /xyz is the basepath of the proxy. You can reference this directly using a built-in variable `proxy.basepath`.

Also, if you want a suburi, you can use the Extract Variables policy - specifically the URIPath element. More on that at https://cloud.google.com/apigee/docs/api-platform/reference/policies/extract-variables-policy#uripat...

 As example -

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ExtractVariables async="false" continueOnError="false" enabled="true" name="EV-suburi">
    <DisplayName>EV-suburi</DisplayName>
    <Properties/>
    <URIPath>
        <Pattern ignoreCase="false">/{suburi-0}</Pattern>
        <Pattern ignoreCase="false">/{suburi-0}/{suburi-1}</Pattern>
        <Pattern ignoreCase="false">/{suburi-0}/{suburi-1}/{suburi-2}</Pattern>
    </URIPath>
    <Variable name="proxy.basepath">
        <Pattern>{basepath}</Pattern>
    </Variable>
    <Source clearPayload="false">request</Source>
</ExtractVariables>

Thank you everyone for your valuable time. Preferably I wanted to use only Javascript to reduce the redundancy of adding extra policies. I used the below script and it worked. 

const supplyUrl = "https://my.supplier/supplier/tariffSelectionG_E5449168?t=randomChars"
  if(supplyUrl.includes('?')) {
    const url = supplyUrl.split('?')
    if(url.length > 0) {
      const tariff = url[0].split('supplier/')
      console.log('tariff:', tariff[1])
    }
  }

That works, too!
